The power supply devices also problems that repeated contacts between a contact device of a body with a contact device of a mobile phone cause the sudden change in voltage between them since they are operated in a contact mode, which leads to poor electrical contact between the contact devices and low stability of the power supply devices. In particular, they are problematic in that a lot of moisture and dusts further aggravate the electrical contact, which leads to the mishaps to the mobile phone and the power supply devices.

• That is to say, thenon-contact charger1 according to the present invention includes aUSB connector10 provided in one side of an encloseddevice body2 to attachably/detachably couple with a USB port of a computer ornotebook computer100 using a jack; aUSB driver block20 coupled to theUSB connector10 and emulated with a USB protocol to receive and transmit data from/to the computer ornotebook computer100; anMPU block30 coupled to theUSB connector10 to control aserial resonator converter50, acurrent sensing block60 and a power supply member, each for receiving a power source from the computer ornotebook computer100 and supplying the received power source to amobile device300, or receiving and transmitting data from/to the computer ornotebook computer100; aprimary coil70 formed on thedevice body2 to generate an induced electromotive force so as to wirelessly transmit a data signal and a power signal from theserial resonator converter50 to themobile device300; and the like, as shown inFIG. 1 toFIG. 10.
• Accordingly, theserial resonator converter50 is such configured that it can convert the data signal received/transmitted between theUSB driver block20 and themobile device300 and the power signal supplied from theUSB connector10 to themobile device300, and sum up the converted data and power signals. And, thecurrent sensing block60 is such configured that it can analyze a signal of thesecondary coil80 to recognize themobile device300, monitor theprimary coil70 and thesecondary coil80 to control a charge voltage to a stable voltage, and transmit a signal of theMPU block30, wherein the signal of thesecondary coil80 is transmitted from theprimary coil70 that senses a load regulation signal by means of thesecondary coil80 corresponding to theprimary coil70 and arranged in themobile device300.
• And, theprimary coil70 is preferably composed of any one of FPCB, PCB, coil and ferrite core in a detachable transformer. For this purpose, theserial resonator converter50 may be preferably configured as a resonant converter for conventional transformers, in particular configured for the purpose of the stable power transmission so that it can be configured as a LLC full-bridge serial resonator converter which is a serial & parallel resonator converter in half wave type or full wave type.

• In addition, the non-contact charger according to the present invention may further include a thermalprotection safety block92 for sensing an internal temperature of thedevice body2, determining a temperature of theprimary coil70 and transmitting a signal to theMPU block30 for the purpose of the circuit cutoff according to the heating in the measured temperature of theprimary coil70 and its high-temperature state; abimetal71 coupled in series to theprimary coil70 to intercept a current flow when a current excessively flows in theprimary coil70 or the internal temperature is increased excessively; a dust &smell sensor circuit90 for sensing dusts and smells inside thedevice body2; and an ionizer high voltage drivecircuit control block91 for generating anions and spraying an antimicrobial spray for the bacterial eradication, as shown inFIG. 1 andFIG. 3. Also, the thermalprotection safety block92 with a temperature sensor for the overheat protection, thebimetal71, the dust &smell sensor circuit90, the ionizer high voltage drivecircuit control block91, and the like are preferably suitably configured in the charging battery-pack200 and themobile device300 that are coupled to thenon-contact charger1 and operated.
• The configuration and operation of thenon-contact charger1 according to the present invention will be described in detail, as follows. That is to say, thenon-contact charger1 according to the present invention is such configured that it can transmit a data between thenon-contact charger1 and themobile device300 and transmit a charging power at the same time using a core-to-core communication mode, themobile device300 having the charging battery-pack200 or the charging battery-pack200 arranged inside of it.
• Such anon-contact charger1 has a communication means for communicating with the computer ornotebook computer100 which can monitor and control states of inner systems of themobile device300, the charging battery-pack200 and thenon-contact charger1. Therefore, as one example, it is shown that the computer ornotebook computer100 and thenon-contact charger1 are communicated to each other by means of the USB communication. This is why the USB communication in addition to the data communication makes it possible to supply the charging power to one line at the same time. However, the data communication between thenon-contact charger1 and the computer ornotebook computer100 is possible in a plurality of data transmission modes such as RS-232c, SISC and serial, parallel transmission modes etc. In this case, thenon-contact charger1 may be supplied with an electric power in conventional separate manners. That is to say, thenon-contact charger1 may be communicated with the computer ornotebook computer100, and simultaneously supplied with a charging power of themobile device300 which is one of the peripherals, and also supplied with an electric power in conventional separate manners, which makes it possible to allow the charging and the data communication between thenon-contact charger1 and themobile device300 at the same time.
• That is to say, the preferred exemplary embodiment of the present invention is a mode of the USB communication between the computer ornotebook computer100 and thenon-contact charger1, and such a USB communication line is ruled so that, among four devices, two devices supply a power source and the other two devices transmit a data. Accordingly, the power source may be supplied to thenon-contact charger1 and the data may be transmitted/received in the USB communication mode. In such a USB communication mode, a host controller is installed inside the computer ornotebook computer100, and therefore the devices connected by means of the lines may be controlled by the host controller. And, aUSB driver block20 of thenon-contact charger1 corresponding to the host controller has a controller for a USB of thenon-contact charger1 installed inside, and theUSB driver block20 converts these information in the USB mode and transmits/receives the converted information to/from the computer ornotebook computer100 according to the conditions of thenon-contact charger1, or if the it is coupled to the charging battery-pack200 or themobile device300 which is coupled to thenon-contact charger1.
• Also, communicating in this USB communication mode is transmitting/receiving the modulated information in theprimary coil70 and thesecondary coil80. And, a controller for the USB communication may also be installed inside the charging battery-pack200, and a controller for the USB communication may also be installed inside themobile device300. Therefore, the controllers communicate with the computer ornotebook computer100 in the USB communication using thenon-contact charger1 as a hub since these communication signals are possibly transmitted through theUSB driver block20 of thenon-contact charger1.
• Accordingly, the non-contact charger1 that communicate a data with the mobile device300 using the core-to-core communication mode and transmits an electric power includes a USB connector10 for coupling with a USB port of a computer and notebook computer100; a USB driver block (USB emulation control block)20 coupled to the computer and notebook computer100 and the USB connector10 to receive music, moving pictures, data from the computer or notebook computer100 and emulate them with a USB protocol; an MPU block30 for controlling internal elements of the non-contact charger (wireless charger)1; a gate drive block40 including a bootstrap gate driver; a serial resonator converter50 which is an LLC full-bridge serial resonator converter; a primary coil70 used as a detachable transformer composed of FPCB, PCB, coil and ferrite core and synthesizing a signal through the control of the MPU block30 and wirelessly transmitting the synthesized signal to the secondary coil80 of the battery-pack installed inside the mobile device300; a bimetal71 coupled in series to a C-L resonator when all functions of the chips are shut down and detachably inserted to ensure its safety when the core (a primary coil70) are overheated; a dust & smell sensor circuit90 for sensing dusts and smells on the non-contact charger1; an ionizer high voltage drive circuit control block91 for spraying an antimicrobial spray for the partial anion generation or the bacterial eradication; a current sensing block60 for stably controlling an electric power through a current feedback using an automatic variation algorithm of primary frequency so as to recognize ID of the charging battery-pack200 in the MPU block30 of the charging module in the primary coil70 through the load regulation in the mobile device having a wireless charging module installed inside of it, the wireless charging module being coupled to the secondary coil80 and arranged in the charging battery-pack200, and to control a voltage of a secondary rectification terminal in the charging battery-pack200; a thermal protection safety block92 for sensing a temperature of the charging chips; and a signal detection block61 coupled to the primary coil70 to detect a secondary signal, the primary coil70 sensing a feedback signal out of the secondary signal in the charging battery-pack200.
• As a result, themobile device300 may use the above-mentionednon-contact charger1 as a hub of the USB communication to receive music, moving pictures, data, etc. from the computer (PC) ornotebook computer100, and further control themobile device300 in the computer ornotebook computer100. For this purpose, theUSB driver block20 coupled to theUSB connector10 emulates the transmitted/received data with a USB protocol, and wirelessly transmits a signal to themobile device300 or the charging battery-pack200 by synthesizing a signal in the primary coil (a detachable transformer: a transformer composed of FPCB, PCB, Coil and Ferrite core)70 through theUSB driver block20 and theMPU block3 and converting the synthesized signal. Therefore, like theprimary coil70, theUSB driver block20 receives a data signal transmitted from the secondary coil (a detachable transformer: a transformer composed of FPCB, PCB, Coil and Ferrite core)80 of the charging battery-pack200 to separate a signal through the frequency shift keying (FSK), and stores the data in a storage medium (memory) of themobile device300. Therefore theUSB driver block20 may store data using theUSB controller301 since it includes theUSB controller301.
• In addition, if the charging battery-pack200 or themobile device300, each having a secondary wireless charging module installed inside, approaches thenon-contact charger1 when thenon-contact charger1 is still in operation, then they may be automatically synchronized in the computer ornotebook computer100 to be automatically contacted by means of the USB communication, and the storage medium folders are popped up in themobile device300 to wirelessly upload and download music (MP3 format), moving pictures (avi, asf, dat format), data, etc. to/from the computer ornotebook computer100.
• That is to say, thenon-contact charger1 coupled to the computer ornotebook computer100 senses the contact of the charging battery-pack200 by allowing theprimary coil70 to transfer a pulse in constant intervals. Then, the wireless data communication possible between theprimary coil70 of thenon-contact charger1 and thesecondary coil80 of the charging battery-pack200. Separately, thenon-contact charger1 may supply an electric power of the USB port in the computer ornotebook computer100, or separate supply powers to the charging battery-pack200. The configurations of thenon-contact charger1 and thebattery pack200, and the mobile device and the like will be carried out using a large number of techniques filed by the inventors. In addition to the charging and data communication mode by the above-mentionednon-contact charger1 andbattery pack200, thenon-contact charger1 and thebattery pack200, and the mobile device and the like are provided in the present invention so that an electric power can be supplied to them and the data can communicate between them, thereby to facilitate the data transmission/reception to/from a controller of a main computer or notebook computer, and the state monitoring, etc.
• And, if thecurrent sensing block60 receives a signal which is proven not to have a memory in which the signal from thesecondary coil80 can receive themobile device300 and music (MP3 format), moving pictures (avi, asf, dat formats), data, etc, then the USB driver block (USB emulation control block)20 further includes a USB datatransmission control module25 not to transmit the USB data (music (MP3 format), moving pictures (avi, asf, dat format), data, etc.) through the control of theMPU block30, and the mobile device may thus transmit data again if the mobile device is proven to be in contact. Then, theprimary coil70 and thesecondary coil80 transfer only an electric power and a data required for the power transfer, and also transmits suitable signals for them to the computer or notebook computer.
• Then, a unique ID is generated in the charging battery-pack200 or themobile device300 in response to the pulse signal of thenon-contact charger1 and transmitted to thenon-contact charger1 via theserial resonator converter50, theprimary coil70 and thesecondary coil80 through the control of theMPU block30 of thenon-contact charger1. That is to say, if a unique ID signal is transmitted through thesecondary coil80 from ID chips in thecharger controller210 of the charging battery-pack200, the ID chips having a secondary wireless charging module installed inside, then the unique ID of the charging battery-pack200 or themobile device300 is recognized by a load regulation signal of the supplied power signal in theprimary coil70, thesignal detection block61, thecurrent sensing block60. If the unique ID of the charging battery-pack200 or themobile device300 is recognized as described above, then information about the charging battery-pack200 or themobile device300 is transmitted to the computer ornotebook computer100. That is to say, if the non-contact charging battery-pack200 is put on thenon-contact charger1, the ID chips installed inside the charging battery-pack200 operate and regulate a load under a non-load state to transmit a charge start ID to thenon-contact charger1, and thenon-contact charger1 feedbacks the signal to confirm that the ID accords as a right signal, and supplies an electric power to the charging battery-pack200 in a full power mode if the ID accords as a right signal.
• And, if the unique ID of the charging battery-pack200 or themobile device300 is recognized, then a voltage of the secondary rectification terminal in the charging battery-pack200 or themobile device300 is controlled to a constant voltage by means of theprimary coil70 and thesecondary coil80. This may control the secondary charging power of the charging battery-pack200 or themobile device300 using an automatic variation algorithm of primary frequency of thenon-contact charger1, minimize a consumed power [Pdis=(Vout−Vbat)*Ichg] by Vdrop in theprimary coil70, thesignal detection block61 and thecurrent sensing block60 of thenon-contact charger1 to reduce separate elements of the secondary charging module in the charging battery-pack200 or themobile device300, and prevent the increase in temperature of other charging chips. Therefore, it is possible to use linear charging IC without the use of the complex and expensive switching charging IC, and to ensure an inner space of the battery-pack.
• Next, different kinds of metal bodies without any of charging modules are heated by the heat which is generated due to the loss by an eddy current by an induced electromotive force when the metal bodies are put on thenon-contact charger1, which leads to the damage in thenon-contact charger1. This phenomenon is one of the problems that have the most serious effect on the stability of thenon-contact charger1 using the induced electromotive force. Therefore, the mobile devices should have a safety device to recognize different kinds of metal bodies, such as coins, metal pens, scissors, etc., without any of charging modules and to shut down an electric power to prevent their overheat.
• As configured above, a means for transmitting an electric power from theprimary coil70 to thesecondary coil80 is to use a half wave or full wave type serial & parallel resonator converter to induce LC resonance, thereby to make an electric current into a sine wave and transmit an electric power to the secondary side by means of the inductive coupling. At this time, the switching frequency is set to a higher level than the resonant frequency to be soft-switched. There is a mechanism for sensing and determining whether different kinds of foreign substance is put on thenon-contact charger1 by applying a PWM pulse at constant intervals in theprimary coil70 for a very short time. The switching frequency and the phase of current is always formed at an angle of 90 degree under an unloading condition. At this time, the phase of current is changed with the change in self inductance if foreign substance approaches theprimary coil70, and a level of the foreign substance is recognized according to the level of phase difference. That is to say, if an approaching matter is sensed, an ID check signal is transferred during a constant period that an electric power is applied. At this time, the approaching matter is recognized as foreign substance if a feedback unique ID signal is not sensed or different ID is sensed, and then a charging system of thenon-contact charger1 is shut down not to supply a charging power to theprimary coil70, thereby to ensure the stability of the charge management block in the charging battery-pack200 or themobile device300.
• That is to say, thecurrent sensing block60 of thenon-contact charger1 generates constant intervals of a PWM pulse in theprimary coil70, and then thecurrent sensing block60 further has a foreign substance detection function that is to give an ID to continuously transmit a data signal and a power signal if constant intervals of a PWM pulse are generated in theprimary coil70 and the detected signal from thesecondary coil80 which is in response of the constant intervals of the PWM pulse is detected as a normal signal, and to sense the detected signal as the foreign substance to suspend the transmission of the data signal and the power signal if there is no response or the detected response signal is not a normal signal.
• Also, complicated techniques are required for this foreign substance detection function to sense the foreign substance during the charging, wherein an electric power gradually falls down with the charging. Hysteresis is put on this power curve, and a matter is recognized as foreign substance if a signal of the matter goes beyond a hysteresis period when the matter is put on thecurrent sensing block60, thereby to use an algorithm to shut down thecurrent sensing block60.
• The present invention may provide a wireless charging solution with the safety and the battery monitoring function of the charging battery-pack200 in thenon-contact charger1, wherein a safety device and wireless charging modules are installed inside the charging battery-pack200.
• In addition, thenon-contact charger1 basically detect temperature of theprimary coil70 and various component chips using the thermalprotection safety block92, or monitors inner temperature of thedevice body2 to prevent an overcurrent flow since thenon-contact charger1 has chips having a shut-down function at a constant temperature over 45° C. and a protection function against the overcurrent and overvoltage, and also prevent an overcurrent flow since thenon-contact charger1 has a fuse installed inside. And, a circuit is intercepted if the functions of the component chips in thenon-contact charger1 is paralyzed and erroneous signals are detected, and then thenon-contact charger1 organizes safety devices, for example to intercept a circuit when theprimary coil70 is overheated, by formingbimetals71 in series in a C-L resonator coupled to theprimary coil70.

• Accordingly,FIG. 2 andFIG. 3 are diagrams showing anon-contact charger1 having an IrDA transceiver module installed inside according to the present invention.
• Referring toFIG. 2 andFIG. 3, if thenon-contact charger1 is connected to a USB port of the computer ornotebook computer100 for the power input, thenon-contact charger1 converts data, such as USB communication protocol and IrDA, to each other using anIrDA signal converter21 installed inside thenon-contact charger1, and engages music, moving pictures, data and the like, which are stored from the PC or notebook computer, through an IrDA transceiver to wirelessly exchange the data with the mobile device300 (mobile phones, PDA, PMP, DMB devices, MP3, etc.). Of course, a battery is charged with an electric power for power supply by transmitting energy to themobile device300 by means of theprimary coil70 and thesecondary coil80 by employing a non-contact detachable transformer.
• If theIrDA port22 installed inside thenon-contact charger1 and the IrDA port of themobile device300 are matched with each other to allow themobile device300, with a secondary wireless charging module installed inside, to approach thenon-contact charger1, then thenon-contact charger1 automatically synchronizes with a computer body by means of theprimary coil70 and thesecondary coil80, as described above.

• And, thecharger body201 may be composed of separated packs separately formed to be detachable and attachable from/to themobile device300. Also, thecharger body201 may be composed of integrated packs arranged inside a body case of themobile device300 to be formed integrally.
• Then, thecharger body201 composed of the separated packs further includes adevice block240 for supplying a power source of therechargeable battery230 to themobile device300 through the control of thecharger controller210.
• A configuration of thecharger body201 will be described in detail with reference toFIG. 1 andFIG. 3, as follows. First, thesecondary coil80 of the charging battery-pack200 is coupled to a full-bridge rectification block81 of the mobile device. And, thecharger controller210 coupled to therectification block81 may transmit a unique ID of themobile device300 or the charging battery-pack (a wireless charge-enabled battery pack)200, sense foreign substance, turn on/off a charging feedback charge circuit, and transmit a charging level to thenon-contact charger1, and it has a signal-to-USB conversion function. And, thecharger body201 may includes acharge management block220 for charging, a fuelgauge control block221, aprotection control block222, a PTC andrechargeable battery230, and aUSB controller301 or anIrDA controller block302 installed inside themobile device300, and the like together.
• And, the charging battery-pack200 is provided with a plurality of safety devices, as in the safety devices of the above-mentioned non-contactcharge management block1.
• That is to say, the safety devices of the charging battery-pack200 feedbacks the distributed voltage because NTC coupled to the outside of the safety devices changes a resistance value according to the change in temperature the presence of a temperature sensor installed inside the charge management block, and therefore the safety devices may function to intercept the charging if the temperature exceeds the previously set temperature. Also, the safety devices of the charging battery-pack200 protect a battery from overcurrent, overvoltage, overdishcarge, short circuit, etc. using the protection block, so called PCM, and also protect the charging battery-pack200 therechargeable battery230, and their circuits since they are shut down by the overcurrent and temperature using PTC or bimetal. And, the safety devices of the charging battery-pack200 may include a mechanism that transmits an erroneous signal to thenon-contact charger1 through the load regulation if an erroneous operation in the safety devices is caused for ID chips installed in the charging battery-pack200 and other many chips during the charging, and then receives a signal from thenon-contact charger1 through FSK and switches thenon-contact charger1 off to suspend a power supply.
• And, this charging battery-pack200 is integrally formed along with themobile device300 since it is arranged inside themobile device300, as shown inFIG. 5 toFIG. 9, or may be separately formed to facilitate its detachment and attachment.

• In general, the above-mentioned non-contact transformer according to the present invention has disadvantages that it has a relatively lower self inductance than the conventional transformers since it has large pores unlike the conventional transformers, and that a circulating current flows according to the change in load if the conventional serial resonant converter is used in the non-contact transformer since it has a relatively larger leakage inductance. In addition, the non-contact transformer according to the present invention has a problem that a switching loss may be caused by the continuous current flow in secondary rectifier diodes, depending on the reverse recovery characteristics of the diodes. However, in order to solve the problems, the non-contact transformer according to the present invention has advantages that its circulating current flow may be significantly lower than if the conventional serial resonant converter is used in the non-contact transformer since a LLC full-bridgeserial resonator converter50 for a non-contact transformer may operate at a lower switching frequency than a resonance frequency, and that a switching loss of the diodes may be reduced since a discontinuous current flows in the secondary rectifier diodes.
• Also, theprimary coil70 and thesecondary coil80 are composed of any one of FPCB, PCB, coil and ferrite core of the detachable transformer, and formed in a flat or cylindrical shape of a circle, tetragon or polygon to facilitate the signal transmission.

That is to say, the charging battery-pack200 is composed of a secondary coil (including a coil or core)80; arectification block81; acharger controller210 which is an adapter control block having a port installed inside, the port being able to enable or disable LDO+ID (TX, RX communication)+an FET drive+a battery charging input (Empty, Full signal) function+an oscillator+a charge management block; a protection control module (PCM)222; a PTC and arechargeable battery230; acharge management block220; adevice block240 which is a device coupled to a mobile phone, etc.
• In the case of the embedded charging battery-pack200, a case cover of themobile device300 has a secondary coil a magnetic field shield (using a method for ejection-molding a coil on a cover, or manufacturing a protective case and subjecting the case to an ultrasonic welding process), and produces a device, which can be coupled to themobile device300, to incorporate a rectification block and a wireless ID detection block into the embedded block of themobile device300 coupled through the device, and then the charging battery-pack200 is charged with an electric power through the device coupled of the battery pack installed inside by employing the DC/DC converter320 and thecharge block330 installed inside themobile device300.

• Blocks for this embedded charging battery-pack200, which is a non-contact charging semi-inner pack applicable to themobile device300, may include a secondary coil (including a coil or core)80; arectification block81; acharger controller210 which is an adapter control block having a port installed inside, the port being able to enable or disable LDO+ID (TX, RX communication)+an FET drive+a battery charging input (Empty, Full signal) function+an oscillator+a charge management block; a protection control module (PCM)222; a PTC and arechargeable battery230; a DC/DC converter320 installed inside themobile device300 as a GSM mobile phone; and acharge block330 installed inside themobile device300 as a GSM mobile phone, as shown inFIG. 6. At this time, themobile device300 as the GSM mobile phone refers to a mobile device (for example, a GSM mobile phone) having a DC/DC converter320 and acharge block330 installed in the device.

• Therefore, a secondary side as the charging battery-pack200 receives AC current from thesecondary coil80 and rectifies the AC current in therectification block81 to convert the rectified AC current into DC current, and generates a power save code for reducing an electric power in thenon-contact charger1 and transfers the generated power save code through a TXD pin if its voltage exceeds stable voltage (for example, 5.5 V), and then by adjusting a voltage of the secondary side to the stable voltage (for example, 5.5 V) using a parameter (frequency). This procedure is repeated to generate ID for a stable voltage (for example, 5 V) if a voltage of the secondary side as the charging battery-pack200 becomes the stable voltage (for example, 5 V) which is an optimum voltage condition, and to generate an electric power in thenon-contact charger1 if the ID of thenon-contact charger1 is matched. If the ID of thenon-contact charger1 is not matched, a power supply is shut down and under a sleep mode in thenon-contact charger1, or an error is caused to shut down a power supply since there in no data reception information for the unique ID when foreign substance is put on thenon-contact charger1.
